Default Rototiller bike... WORKS

so here it is.
I am one of the few people to use a rototiller on a bike... I do not know why! it is very fast! this friction bike uses a mag-lite (could not find a bike beg...) for a spindle. the mag-lite has washers that keep it from slipping on the wheel (to the side) the mag-lite is bolted to a piece of the clutch.

(i do not know why it looks crooked but i assure you it is not...)

the motor can be lifted up to start and then lowered to go
it uses a craftsman rototiller engine, and i had to have it tipped just right so it DOES get gas flow

POTENTIAL PROBLEMS INCLUDE:

my first two spindles broke, but this on will probably hold

anyway
the only other prob is the first bolt to support it was put on with a crappy wielder, but my kind nieghbor fixed it with his arc wielder.

so yea i just thought i could inspire someone to make another cuz ive only seen very few.

The knurled part of the mag light is a fairly good material but you're only using half of the knurled part on the tire and the rest is the smooth part. Mag lights are fairly expensive compared to pipe fittings or bike pegs. It reminds me that the on/off button (the rubber part) fell out of every maglite I ever owned. I don't guess they ever fixed that little problem.

The Mag-Lite is a good idea because it's easily replaced when worn, maybe even cheap too.

Your engine should have to be tipped "just right" to get fuel flow, it has a diaphram carb on it doesn't it?

my engine gets perfect gas flow... YAY, but im having problems with the maglite bolt. the bolt thru it keeps striping and it wont stay in. its bolted onto metal (unknown) that wont wield without an arc wielder. an arc wielder is not controlled enough, to handle this small job tho... any suggestions for my little predicament

Try JB Weld, or Loctite sleeve retainer.

That is very interesting set-up. I have been going to garage sales and
have manage to pick up 3 Mantis tillers very cheaply, with the dual sided gearboxes and
was thinking they could be modified into push trailer set ups.

As to your drive. If you could weld a few empty nuts 1/2 inch together, to make one long nut. Then you could run an all thread 1/2 rod through a skateboard wheel and bold it onto the drive shaft you already have the threaded rod on. Just bolt it off and on to make interchangeable wheels. I did that to an e motor and it worked pretty well. The soft rubber wheel is much easier on the tires. I am running pneumatic tires on my Rhino bike and there is no more wear than if it were running on sand.

Looks like a great build. keep up the good work
